SIPHON.

SPECIFICATION forming part of Letters Patent No. 756,517, dated April 5,1904.

Application filed August 21, 1902.

To a, w/wm it nm l concern.-

Be it known that I, CAMILLUs MILLER, a citizen of the United States,residing at Sunflower, in the county of Beaver and State ofPennsylvania, have invented a new and useful Siphon, of which thefollowing is a specification.

This invention relates to siphons such as are used for drawing liquorsof various kinds from casks or other receptacles; and it has for itsobject to provide a device of this class which shall be especiallyapplicable to bottling the liquids thus drawn.

WVith this end in view my invention con- SlStSiIl an improvedconstruction and arrangement of parts whereby the siphon is providedwith a number of discharge-tubes, each having means for connecting itwith the neck of a bottle or other receptacle.

The invention further consists in the combination, with eachdischarge-tube, of an airtube and a floating valve for closing the same,thereby preventing overflow, while not interfering with the filling ofthe bottles or receptacles to any desired point, which may be regulatedby properly adjusting the airtubes.

The invention further consists in the combination, with my improvedsiphon, of a filter of suitable construction to prevent the entranceinto the siphon of foreign substances which might interfere with itssuccessful operation.

The invention further consists in the improved construction andarrangement of the detailed parts of the device, which will behereinafter fully described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view of myimproved siphon, showing the same in position for operation, several ofits discharge-tubes being connected with bottles to be filled and onesuch discharge-tube being closed by a clamp, such as is used when thetube is temporarily out of use. Fig. 2 is a sectional view of the filterand the tube upon which it is mounted. Fig. 3 is a side view, partly insection, showing one of the valves used in connection with my invention.

' Corresponding parts in the several figures Serial No. 120,547, (Nomodelfi are indicated by like characters of reference.

1 designates the barrel of a pump, which is of ordinary construction andthe purpose of which is simply to start the flow in the siphon of whichthe said pump-barrel forms a part.

2 is the pump-handle, and 3 the piston-r0d, of which only the upper endappears in the drawings.

4 designates a bung or stopper, which is mounted slidingly upon thepump-barrel and which serves to engage the bung-hole of a cask. fromwhich the liquid is to be drawn, the said bung being madertapering, asshown, and constructed, preferably, of rubber in order to insuredurability, as well as to enable a tight joint to be made.

The lower end of the pump-barrel has suitably connected therewith aflexible tube 5, at the lower end of which is mounted the filter orstrainer 6. The latter is composed of an annular casing of wire-netting,the said casing being composed of inner and outer walls 7 and 8,connected at their upper and lower ends with annular bands 9. At theupper end these bands are permanently connected with a cap 10, having anupwardly-extending flange 11, by means of which it may be connected withthe lower end of the flexible tubing 5. In Fig. 2 of the drawings atubular reducingsection 12 has been shown as interposed between theflange 11 and the tube 5. The annular casing composing the filter isclosed at its lower end by a detachable catch 13, and the annular spacebetween the walls of said casing is to be packed with suitable strainingor filtering material 14:, such as cotton or the like.

It will be observed that by this construction a large straining orfiltering surface is formed. It will further be seen that there isabsolutely no obstruction to the entrance of the liquid into the lowerend of the flexible tubing 5, the

space between the latter and the inner wall of the annular casing beingincreased by the use of the reducing-section 12, as will clearly appearby reference to Fig. 2 of the drawings.

Suitably connected with the pump-barrel, near the upper end of thelatter, are a series of discharge-tubes 15, of which any desired numbermay be used. In the drawings the pump-barrel has been shown as providedwith a series of laterally-extending discharge-tubes 16, upon which theflexible tubes are held by frictional contact therewith. The dischargeend of each of the tubes 15 is fitted to slide vertically through asuitable opening or perforation in a tapering stopper 17 made,preferably, of rubber and adapted to fit in theneck of the bottle orreceptacleto be filled. Fitted in each of the stoppers 17 to slide inthe same Vertically is an air-tube 18, which may be made of metal,-hardrubber, or other suitable material and which carries at its lower end acage 19, connected therewith by screw-threads 20 and containing afloating valve 21, adapted to engage the seat 22, formed in the upperend of the valve-cage at the juncture of the same with the air-tube. Theconstruction of the floating valve 21 embodies the valve proper, 23,which is made, preferably, of rubber and which is connected by avertical pin 24 with a float 25, which may be constructed of cork, lightwood, or any other suitable material. The pin 24, which connects thevalve with the float, is extended upwardly into the lower end of theair-tube, thus forming a guide the action of which will be to preventthe valve from being tilted, thus insuring the certainty of its beingbrought into engagement with the seat when the device .is in operation.

It is obvious that the construction of the floating valve might bechanged or modified without detracting from its utility. Thus,

for instance, a hollow float might be employed or other means than theguide-pin might be employed for connecting the valve with the float.Again, the valve and float might be made integral with each other, aswell as with the pin 24:, if so desired. I prefer, however, theconstruction herein shown on account of its simplicity, inexpensiveness,and certainty of operation.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation of my invention and its advantages will bereadily understood. To start the siphon in operation, the pump-barrel 1is connected with the cask or vessel from which liquid is to be drawn bymeans of the bung 1. The flexible inlet-tube 5 may obviously be made ofany desired length suflicient to permit the filter to rest upon thebottom of the cask. The stoppers 17 at the discharge ends of theflexible discharge-tube 15 are adjusted in the necks of the bottles orvessels to be filled, and the air-tubes 18 are adjusted in said mamstoppers to regulate the point to which it is desired to fill suchbottles, the inlet of liquid through the tubes 15 being obviouslychecked when the outlet of air is closed by the floating valves. Theflow in the siphon is now started by means of the pump, and the liquidwill run into the bottles or receptacles unti the same have been filledto the desired point, when the exit of air being prevented by theclosure of the floating valves the liquid will cease to flow. Thedischarge-tubes may now be shifted from the filled receptacles to emptyones by compressing the said tubes between the thumb and finger whilethe transfer is be ing made. It. is obvious that by the proper use ofthis device overflow is made absolutely impossible, thus avoiding waste,as well as the absolute necessity of constant and close attention.

If it shall not be desired to use all of the discharge-tubes, one ormore of them may be temporarily closed by adjusting upon the dischargeends of the same ordinary c0mpressing clamps, such as are shown at 30.It is obvi-- ous that the use of such clamps upon one or more of thetubes will not interfere with the operation of the remainder of thedevice.

While I have in the foregoing described the preferred construction of myinvention, I desire it to be understood that I do not limit myself as tothe details of the same, but consider myself entitled to anymodifications which may be resorted to without departing from the spiritof my invention.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States In a siphon, the combination of apump-barrel, flexible discharge-tubes connected therewith, a flexibleinlet-tube at the lower end of the pump-barrel, a strainer mounted atthe lower end of said inlet-tube and consisting of an annular chamber acap covering said chamber having an interior annular flange, and areducing-tube interposed between said flange and the flexibleinlet-tube, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signaturein the presence of two witnesses.

CAMILLUS MILLER.
